Note: if the original imageBitmap has been use for display, the source surface will have been cropped and
the original cropping IntRect has been lost, in this case use cropped mSurface instead of mdata.

If some of the new clip rect falls outside the source we have to crop the source if it hasn't been cropped.

Q: Should I attempt to get tests for this added to WPT?

Bug 1723674 added a new nsID::GenerateUUID() static factory function to generate UUIDs without the overhead of querying and instantiating an nsIUUIDGenerator object. nsContentUtils::GenerateUUID() is a utility function that amortizes that overhead by holding an nsIUUIDGenerator singleton. That's no longer necessary because code that calls nsContentUtils::GenerateUUID() can now just call nsID::GenerateUUID(). No nsIUUDGenerator is needed.

nsIMediaSource objects.

a MediaSource from an associated Permission object.

Based on our previous patches, we only support default behavior for
source and scroll-offsets:
1. source:auto
2. scroll-offsets: none
3. scroll-offsets: auto, auto, ...

So update the parser for them. We expect to remove whole
@scroll-timeline in Bug 1733260, so now only do a tiny update in parser.

Differential Revision: https://phabricator.services.mozilla.com/D132417

Per spec, "auto" represents the scrolling element of the document.
However, the scrolling element might be changed, based on the layout, in
quirks mode. Besides, the content of the root scroll frame is the root
element, instead of the scrolling element (e.g. body element) in both
standard and quirks modes. So now we define a special type, Scroller, to
represent the source of scroll-timeline, and use its |mType| to decide
which scroll frame we would like to use. In addition, hope this change let
us easier to implement nearest scroller.

Note: for auto scroller, we register this ScrollTimeline to the root
element, in both modes. Once we expose ScrollTimeline interface to the
script, we can rely on the |mType| of Scroller to return the correct
source element, whether it is scrolling element or not.

Bug 1676791 - Part 8: Hook scroll-timeline rule into Cascade data and use it for CSS animations. r=emilio,hiro

We hook the rule into cascade data, and so we can look it up by timeline
name. Now we only use StyleScrollDirection from @scroll-timeline rule.
`source` and `scroll-offsets` are skipped now and use the default values
instead because I'm pretty sure the syntax will be changed in Bug 1733260,
and `scroll-offsets` may be obsolete because the spec proposal intents to
make it be always 0% ~ 100%.

Also, add some reftests for the default `source` and `scroll-offsets`,
and different `orientation`s.

Besides, we disable at-scroll-timeline-start-end.html in Gecko because
we don't support start/end descriptors, and there are too many
intermittents in it.

For simplicity purposes, we don't consider OMTA for now. OMTA support
for scoll-timeline will be done in Bug 1737180.

However, in this patch, we would like to address:
if the geometic animations use scroll-timeline, we don't have to let it
affect the transform animations on the same animation target:
1. If we don't do scrolling, its geometric properties don't change, so no
   effect on transform-like properties.
2. If we do scrolling, we may un-throttle the transform animations by
   other ways, e.g. Keyframe::CanThrottle(). So we don't need to worry
   about this.

Note: tests are in the next patch.

Based on https://github.com/w3c/csswg-drafts/pull/4842, we define
"has finite timeline", which is a timeline that's not monotonically increasing.
We need this to update start time and hold time for scroll-timeline, so
we play scroll-linked animations as we expected, e.g. GetLocalTime() returns
the correct time value from GetCurrentTimeAsDuration().

Known issue: we still have bugs when setting "animation-play-state:paused".
Will do that in Bug 1741255.
